Method of manufacturing an elongated label supply

ABSTRACT

A label structure includes a base sheet, a top sheet, and a barrier sheet therebetween for preventing ink or print media transfer between the top and base sheets. The top sheet is removable in its entirety. Paper, clear and other base sheets are contemplated. A preferred method for manufacturing the label structure includes printing a top web, applying glue to both sides of a barrier web, joining the top web to the barrier and another side of the barrier to a base web and carrier web composite, die cutting top sheets, barrier sheets and base sheets from said respective webs, and on the carrier web, and thereafter rolling the carrier web with separate label structures thereon to form a rolled label supply.

This is a division of application Ser. No. 450,538, filed Dec. 17, 1982.

BACKGROUND OF THE INVENTION

This invention relates to coupons and labels and more particularly tocomposite coupons and labels and to manufacturing processes therefor.

My U.S. Pat. No. 4,281,762 discloses a composite in-store coupon havinga top sheet and a base sheet wherein the top sheet has side portionspermanently secured to the base sheet and a removable central couponportion free of adherence to the base sheet. A central portion of thetop sheet is detachable from the side portions and serves as aredemption, discount or promotional coupon, for example. This, ofcourse, leaves the side portions with the base. Any copy or art work tostay on the removed coupon must be disposed with the confines of theremovable center area.

Where it is desired to reduce the overall label structure size, a topsheet with no side portions is provided, and the copy or art work isprinted thereon from one edge to another. Applicant has previouslymanufactured and sold a prior art label structure such as this,including a composite label having a removable top sheet which isadhesively, but removably, secured to a base sheet. The entire top sheetis removed from the base sheet and the top sheet does not retain anysticky adhesiveness, or tackiness. Adhesives known in the industry as"fugitive" adhesives provide this removal function wherein no adhesiveremains on the base. Such an adhesive is, for example, the adhesive soldas "EASY OFF" adhesive by Adhesive Products of New York, N.Y., undertype production formula designation 1167-S2.

In manufacturing this structure, both sides of a top web are printed,the upper side of a pressure sensitive base web is printed, fugitiveadhesive is applied, the webs are joined together, and thereafter thewebs are die cut on a backing or liner web, all on the same equipment,to define individual labels, having top and base sheets, disposed on thebacking web. This is similar to the manufacture of labels under theaforesaid patent, except that a fugitive adhesive is used and noperforations are cut to define side portions in the top sheets.

Such a procedure requires the use of a significant amount of adhesive;more so than would be used in other circumstances as will be explained.This use of excessive adhesive is believed to cause significant visualimperfections in the finished label, upon top sheet removal. Theseimperfections are believed to be due to the transfer of ink, or printmedia, between the top and base sheets, while the ink and the glue arestill wet or viscous, spoiling the appearance of the receiving sheet.

More particularly, it is desirable to manufacture a label supply ofcomposite labels on web fed printing apparatus running at speeds, forexample, of 200-300 feet per minute. A top web is printed, for example,joined on the fly to a moving base web to which fugitive adhesive hasbeen applied, and thereafter the top and base webs are die cut on thefly into individual labels. Due to the rapid movement of the two websduring joining and die cutting, it will be appreciated that it isdifficult to maintain proper register between the webs, and between thetop and base sheets during and after die cutting.

To insure proper register and orientation of the sheets, it has beenfound preferable to use a significant amount of the "fugitive" adhesive.Such adhesive, in its wet form, tends to hold the top and base sheetstogether during and after die cutting, and until the adhesive latercures. Use of excess amounts of such "fugitive" adhesive, while requiredfor sheet orientation, is expensive.

It would be possible to use significantly less adhesive if the ultimatereleasable securement of the sheets was the only goal, however, themanufacturing speeds and process require use of more adhesive than isotherwise required.

Normally, and apart from the added cost of the excess adhesive, its usewould not present any problem. However, due to machine speed, and sinceat least the top web is printed immediately before joining to the baseweb by wet adhesive, the ink or other print media is still wet or dampwhen the top web is joined to the base web. It is believed that the wetor damp ink coalesces or otherwise transfers from the top sheetunderside to the adhesive, and then to the base web, or remains with anysmall amount of adhesive which might be left with the base web when thetop sheet is eventually removed as a coupon. Of course, a similar resultis obtained when the base web is printed on the same press, and base webink may transfer to the underside of the top sheet or removable coupon.

This transfer of ink or print media between webs or sheets isundesirable and occasionally spoils an otherwise acceptable print job.Any ink or other print media on the base is particularly distracting anddetrimental.

SUMMARY OF THE INVENTION

Accordingly, it has been one objective of this invention to provideimproved composite labels and coupons.

A further objective of this invention has been to provide an improvedprocess for manufacturing a composite label supply.

A further objective of this invention has been to provide a compositelabel including a removable top sheet, printed on its under side, and abase sheet, all without ink or print media transfer between the sheets.

To these ends, a label according to a preferred embodiment of thepresent invention includes a pressure sensitive base sheet and a lineror backing, a top sheet, and a clear barrier sheet therebetween.Respective adhesive layers between the barrier sheet and the top sheeton one side, and between the barrier sheet and the base sheet on anotherside secure the composite structure together. Preferably, the undersideof the top sheet is uncoated paper and the top side of the base sheet iscoated paper. Under this condition, the top sheet can be removed whilethe clear barrier sheet sticks with the base. A small portion of the topsheet overlaps the adhesive securing the top sheet to the barrier tofacilitate top sheet removal.

Also, and in this embodiment, it is no longer necessary to use a"fugitive" adhesive. A less specialized, general purpose and less costlyadhesive can be used. Thus, and even though a relatively large amount ofadhesive may be used to prevent the components from skewing duringmanufacture, the cost is not as great.

A label supply, according to a preferred embodiment of the invention,includes the aforementioned composite label and an elongated carrierbacking, liner, or release web on which the labels are mounted by thepressure sensitive adhesive. After manufacture, the web is rolled into aroll to provide a rolled label supply.

In a preferred process of manufacturing the aforesaid labels, a top webis printed on one or both sides, glue is applied to both sides of abarrier web, and the top web and barrier web are joined with a base weband carrier web composite. Thereafter, separate labels are die cut todefine composite label structures on the carrier web. In addition, ofcourse, the base web can also be printed.

The barrier sheet inhibits transfer of any ink or other print mediaused, between the top and the base components of the label. The wet ink,even if it coalesces with the adhesive on either side of the barrier,cannot transfer through the barrier. Moreover, the glue between the topsheet and barrier, even though it is not a fugitive glue, all tends toremain with the top sheet when it is removed from the barrier, due tothe use of uncoated paper, so that even if any ink coalesces into theglue, it simply remains therein over the area on the top sheet fromwhich it came. It is thus not left on the barrier nor, of course, on thebase.

It will be appreciated that the invention provides significantadvantages. First, general purpose adhesive can be used and no specialexpensive glues are required between the top and the base sheet.Secondly, enough of the adhesive can be used to maintain register andorientation between the top and base sheets, but without undesirable inktransfer therebetween. Moreover, paper base sheets can be used withease, and without undesirable ink transfer or spoiling.

These and other advantages will become readily apparent from thefollowing detailed description of a preferred embodiment of theinvention, and from the drawings, in which:

DESCRIPTION OF THE PREFERRED EMBODIMENT

Turning now to FIG. 1, a portion of a label supply according to theinvention is shown in cross section. The rolled label supply 10 includesan elongated carrier, release liner, or backing web 11. Mounted on theweb 11 is a preferred composite label structure 12 according to theinvention. The composite label structure 12 includes a removable topsheet 13, a barrier sheet 14 and a base sheet 15. Layers of adhesive, 16and 17, lie between the top sheet 13 and barrier sheet 14, and betweenthe barrier sheet 14 and the base sheet 15, respectively. Also, a layerof pressure sensitive adhesive 18 is disposed between the base sheet 15and the web 11.

It will be appreciated that the top sheet 13 has an upperside 13a and alower or underside 13b. The barrier sheet has an upper or top side 14aand a lower or underside 14b. The base sheet 15 has an upper or top side15a and a lower or bottom side 15b. As will be later described withreference to FIG. 7, top sheet 13 has a portion 13c, which may be a fulledge portion or just a corner portion, overlapping first adhesive layer16.

Turning now to FIG. 2, a label structure according to the invention isshown in use in connection with a product 20. A base sheet 15 is mountedon a surface 21 of the product by means of the pressure sensitiveadhesive 18 (the composite label structure 12 having been removed fromthe liner web 11 and applied to the product 20).

As shown in FIG. 2, the top sheet 13 has been removed from the basesheet 15. This would occur at point of sale, for example, where apurchaser desires to use the top sheet 13 for the purposes of aredemption, discount, or the like, depending upon how the labelstructure is utilized in connection with the product.

It will be appreciated that the top sheet 13 is preferably the same sizeas the base sheet 15, and is preferably coextensive therewith. It willalso be appreciated that the base sheet 15 remains with the product 20,while the top sheet 13 is removable therefrom.

Turning now to FIG. 3, there is shown in that figure a diagrammatic viewillustrating the manufacture of a rolled label supply, according to theinvention, on a single apparatus. The manufacturing operation andprocess is preferably conducted on a printing apparatus, known in theindustry as a "Mark Andy", Model 2100, In-Line, Flexographic Printing,Die Cutting, and Laminating Press. Such apparatus is available from MarkAndy, Incorporated, 18081 Chesterfield Airport Road, Chesterfield, Mo.63017. While any other suitable apparatus may be useful for forming thecomposite label structure of the invention, this apparatus isparticularly useful as will be described.

Considering now the details of FIG. 3, a rolled, elongated, coupon ortop web 30 is illustrated at the lefthand area of the figure. Thiscoupon web includes material which will eventually define the top sheet13 of the label composite 12.

This web is run through a print station 31 which prints one side of theweb, turn station 32, which turns the web over in a well known maner,and additional print stations 33 and 34 which print opposite sides ofthe web. Accordingly, an underneath side of the web corresponding to theunderneath side 13b of the top sheet 13 is printed at the first printstation 31 while the top side of the web corresponding to surface 13a ofthe top sheet 13 is printed at stations 33 and 34. Thereafter, the web30 is directed to a joining nip 35 where it is joined with the othermaterials of the invention as will be described.

It will be appreciated that the web 30 can be run through varyingnumbers of printing stations, and on any side, to produce desiredmulti-color printing on either or both sides of the web.

The barrier sheets 14 are initially provided in elongated web rolledform, as shown at web 40 in FIG. 3. Preferably, this web is slightlynarrower than the top sheet web at this time, and later diecutting ofthe composite cuts all three webs into structures where top sheet,barrier and base sheet are generally coextensive. Alternately, thebarrier sheet may be left slightly narrower than the top sheet in cutform. In either structure or process, a cleaner operation, with no trampedge glue, is the result.

Preferably, the barrier material is purchased in rolled, elongated websin pre-print treated condition. The print treating is believed topromote adhesion to the other webs. Such print treating operations arewell known in the art and include electronic corona discharge, flametreatment or ony other known treatment means.

Web 40 can be print treated on the press equipment of a print treatingstation 41 (FIG. 3) which subjects the web to a print treatingoperation.

The barrier web 40 comprises preferably a clear transparent film madefrom, for example, polypropylene, polyester, or acetate. For desiredapplications, the barrier could be translucent or opaque, instead ofclear and transparent. Also, the barrier could be pre-printed.

The barrier web 40 is directed through a double side glue treatmentstation 45 where adhesive is rolled onto both sides of the barrier webin any suitable manner well known in the art. This glue station 45 isoperable to apply a layer of adhesive to each side of the barrier web,and preferably, slightly inboard of the barrier edges, and at leastalong one edge thereof (FIG. 6). Also, layer 16 is preferably slightlynarrower than layer 17, at least along one longitudinal edge so as toprovide a non-adhered top sheet portion as will be described. Suchadhesive, according to the invention, can be any suitable, generalpurpose adhesive. Preferably, an adhesive such as Adhesive No. 1533X,sold by Fuller Adhesives of Minneapolis, Minn., is utilized in apreferred embodiment of the invention. From the glue station 45, thebarrier web 40 is directed to the nip 35 for joining with othercomponents of the label structure.

An elongated base web, which will ultimately correspond to the pressuresensitive base sheet 15 is provided, together with the elongated releaseliner or backing web 11. This composite pressure sensitive base web andliner is jointly identified by the numeral 50 in FIG. 3. This web isdirected also to the nip 35.

Accordingly, and at nip 35, the web 30 and the composite web 50 arejoined to opposite sides of the barrier web 40.

It will be appreciated that the web 30 has been printed on the sameapparatus at the various print stations and that the entire operationruns at a speed of approximately 200-300 feet per minute, that being theapproximate speed of each of the individual webs. Accordingly, and inthe operation shown in FIG. 3, the web 30 is printed on the apparatuswhile the composite web 50, eventually to comprise portions of the basesheets 15, are not printed.

If it is desired to print the base sheets, they can be printed on thesame apparatus as shown in FIG. 3. To accomplish this, the web 30 couldbe printed, for example, at the first print station 31. Thereafter, theweb 30 bypasses the second and third print stations 33 and 34. Theelongated composite web 50 is run through the print stations 33 and/or34 and hereafter around the barrier web to a position beneath thebarrier web 40 at the nip 35.

In FIG. 3, then, the composite web 50 is shown in a position where it isnot printed on the apparatus, this being for clarity and illustration inthis particular explanation. It will be appreciated that it can beprinted on the same apparatus as well as web 30.

A cross section of the still uncut composite web structure is shown inFIG. 6.

After running through the joining nip 35, the composite formed by theweb 30, the barrier web 40 and the composite, pressure sensitive baseweb and backing 50, are introduced into die cutting station 60. Diecutting station 60 is operable to cut through the respective componentsof the apparatus, down to the carrier or liner web 11. A cross sectionof the still uncut composite web structure is shown in FIG. 6. In thisfigure, the yet uncut barrier web is inboard of the top web and baseweb, and adhesive layer 16 is inboard of the edge of the barrier web.The die cutting edge is diagrammatically shown to produce a cut "C"through the respective components to leave separate labels with an edge,as shown in FIG. 7.

Considering momentarily FIG. 6, then, at the die cutting station, thedie apparatus is operable to cut through the top web to define a topsheet 13, the barrier web to define a barrier sheet 14, adhesive layer17 and the base web to define a base sheet 15, but leaves intact thecarrier or backing web 11. Any suitable well known die cutting operationcan be utilized to provide this die cutting function.

After the individual label or coupon structures 12 are cut, the entirecomposite 10 is directed through a waste remnant station 65 where amatrix 66 is drawn away from the individual composite labels 12 and thebacking 11. This is illustrated in FIG. 4.

Thereafter, it will be appreciated that the carrier web 11 is thereafterrolled to provide an elongated rolled label or coupon supply ofindeterminate length, including a carrier web 11 and individual andseparate composite label or coupon structures 12 thereon, forming therolled label or coupon supply 70 as shown in FIG. 3. Alternately, thesupply can be fan folded, or otherwise handled, however, the rolled formis most common.

In one use of the supply 70, in a coupon applying operation, forexample, the rolled coupon supply 70 is delivered to an applicationapparatus of any known type. For example, one form of such apparatus isdiagrammatically illustrated in FIG. 5. This apparatus serves to bendthe backing web 11 sharply away from the coupons and then attaches thecoupons to a product 20 by means of an airblast or some mechanical meanswhich do not form part of this invention. The pressure sensitiveadhesive 18 on the rear side of the respective base sheets 15 adheresthe composite coupon structure to the product.

While this is only one manner in which the coupons can be applied, itshould be appreciated that the composite construction of the structure12 greatly facilitates the application of coupons to products 20 by themeans illustrated in FIG. 5. When the backing web 11 is bent sharplyaround a corner, such as corner 71, the coupons should remain rigid soas not to bend before actually engaging the product 20. Such bendingcould cause folds in the coupons, misregistration, sticking of thecoupon to itself, or other undesirable circumstances. Light, single plycoupons or pattern gummed coupons, for example, tend to bend or to droopin such an operation, or in the case of pattern gummed coupons tend tohave an ungummed portion hit the product first. When the gummed portionimmediately thereafter engages the product surface, it may do so in sucha position as to cause wrinkles in the coupon. These difficulties resultin poor coupon indexing and placement on the products. At the least,poor coupon control between the point of removal from the backing andthe point of application to a product 20 can result. In this invention,the multiple composite construction of the coupon structure produces arelatively rigid workpiece, greatly facilitating control, placement andhandling without unnecessary bending, drooping, folding, wrinkling orthe like.

Returning now to FIGS. 1 and 7, it will be appreciated that in theindividual cut label structure, the barrier sheet 14 is preferably ofthe same size as the top sheet 13 and the base sheet 15. It will also beappreciated that the adhesive layer 17 extends across the barrier sheetto that sheet's edges, but that layer 16 is short of the edge of topsheet 13 and barrier sheet 14. This facilitates later top sheet removal.

Removal of the top sheet from the barrier and base is illustrated inFIG. 7, which illustrates the top sheet 13 being removed from thebarrier 14 and base sheet 15. This is greatly facilitated by non-adheredportion 13c of the top sheet which overlaps the adhesive layer 16 eitherat a label corner, or along the full edge of top sheet 13.

It will be appreciated, then, in the operation illustrated in FIG. 6,the top sheet 13 can be completely removed from the barrier sheet 14,base sheet 15, and the remainder of the composite structure 12. In orderto insure that the barrier sheet remains with the base sheet 15, thevarious components of the label structure are so selected such that theadhesive between the top sheet 13 and the barrier sheet 14 permit suchremoval, while the adhesive layer 17 between the barrier sheet 14 andthe base sheet 15 tends to stick the barrier sheet onto the base sheet15 in a more permanent fashion.

In particular, I have discovered that when the base sheet 15 ismanufactured of coated paper, it does not permit the adhesive layer 17to soak into the base sheet, thereby leaving more adhesive 17 to securethe barrier sheet 14 to the base sheet 15. On the other hand, the papertop sheet 13 is preferably made with at least an underside, 13b,uncoated. Since that underside 13b is uncoated, the adhesive 16 tends tosoak into the top sheet 13 and not as much adhesive is left between thetop sheet 13 and the barrier sheet 14. Accordingly, the barrier sheet 14tends to remain with the base sheet 15, while the top sheet 13 tends tomore readily pull away from the barrier sheet 14.

Accordingly, in this preferred embodiment, the label structure 12includes a top sheet 13 which can be printed on both upper andundersides 13a and 13b, and a base sheet 15 which, if desired, can beprinted on an upper side 15a. Once the top sheet 13 is removed, thebarrier sheet 14 remains secure to the base sheet 15, covering andprotecting the base sheet.

Moreover, it will be appreciated that the adhesive layer 16, due to theuncoated nature of the paper of the top sheet 13, tends to remain withthe top sheet 13. Where the top sheet 13 has been printed on itsunderside 13b with ink or other print media, and where that ink or mediais still wet or uncured, it is possible that the ink or media maytransfer into or coalesce with the wet adhesive layer 16. Nevertheless,since most of that adhesive is removed with the top sheet 13 when thetop sheet is peeled away, the ink does not transfer to the barrier sheet14 or to the base sheet 15. Thus, the remaining portion of the compositelabel structure 12 is not spoiled by ink transfer thereto from the topsheet, as it might be where the paper base sheet was not covered by thebarrier which is more resistant to the sticking of the glue.

Also, it will be appreciated that as much glue as necessary can beutilized in order to maintain the register between the base sheet 15,the barrier 14 and the top sheet 14 throughout the web joining and thedie cutting, waste remnant removal, and the rolling stages as shown inFIG. 3.

Of course, while the foregoing description has been directed to acomposite structure having a base sheet of paper, wherein the barriersheet is particularly effective to help block ink transfer from topsheet to base sheet, and to serve as a protective film for the basesheet once the top sheet is removed, the base sheet can be made oftransparent or clear material, such as acetate.

Finally, it should be appreciated that many various types of printingcombinations or graphic display can be provided by this invention. Forexample, both sides of the top sheet and the top side of the base,whether paper or clear, may be printed or otherwise decorated. Inanother example, the top sheets could be printed on one or both sideswhile the base sheets are clear, permitting package graphics or printingto show through, once the top sheet is removed. Alternately, a clearbase sheet could be pre-printed.

In any event, the invention provides a large amount of total area forprinting, including the areas over both sides of the top sheet and atleast an upper side of the base, and without ink transfer or spoilingbetween sheets. No tabs or other top sheet parts are left on the basewhen the top sheet is removed.

Accordingly, it will be appreciated that the invention provides acomposite label structure including a base sheet, a removable top sheetand a barrier sheet which prevents ink or print media transfer betweenthe top sheet and the base sheet. In a preferred embodiment, the topsheet is removed from the barrier sheet and base sheet, which remaintogether, the barrier sheet covering and protecting the base sheet andany material printed thereon.

It will be appreciated that this label structure does not require thecoupons or labels to be perforated, nor does it require any other meansfor tearing a portion of one sheet from another portion of the samesheet during the removal process. Also, it will be appreciated that theundesirable ink or print media transfer between the top sheet and thebase sheet are prevented, and the base sheet can be made of paper orclear base materials, as described herein.

These and other modifications and advantages will be readily apparent tothose of ordinary skill in the art, without departing from the scope ofthe invention, and applicant intends to be bound only by the claimsappended hereto.
